UN ambassador says Libya attack was spontaneous

WASHINGTON (AP) — The U.S. ambassador to the United Nations says the attack on the U.S. Consulate in Benghazi, Libya, was spontaneous.

Susan Rice says the current U.S. assessment shows it was not a coordinated, premeditated attack.

But Rep. Mike Rogers, the House Intelligence Committee chair, says it's too early to tell. He says classified intelligence gives pause to those who suggest attacks throughout the Middle East were coincidental.

Rice tells "Fox News Sunday" that protesters gathering near the consulate were joined by others with extremist ties. She says they brought heavy weapons possibly left over from the Libyan revolution last year.

The FBI has an ongoing investigation into the attack spurred by an anti-Muslim video produced in the U.S. that killed Ambassador Chris Stevens and three other Americans.
